ExtReme Chassis Engine Accessories

Compared to old school engines, oil pan sumps on late model LSX engines have grown in length, width and depth. Unfortunately, attempting an LSX conversion with these factory pans often runs into clearance problems with the steering linkage and frame cross members as well as ground clearance issues on lowered vehicles. To alleviate these issues ATS engineered a totally new pan that compliments our ExtReme chassis.

Our high clearance LSx oil pans are hand fabricated laser cut sheet metal and includes a built in windage tray and internal baffling to keep the oil off the crank and surrounded around the oil pump pick up in hard cornering. Oil plumbing ports allow for an external oil filter kit and oil cooler assemblies.

This pan requires a remote mounted oil filter and lines and easily allows the addition of an oil cooler if desired. Below is a list of parts that will complete your remote oil filter installation. This is available as a kit from us.

1 AN -12 120* or 150* Hose End

3 AN -12 90* Hose Ends, 2 for the pan and one for the filter mount

2 AN -12 to -12 O-ring Adapters

10 feet of AN -12 Hose

1 Moroso Remote Filter Mount #23764, or Equivelant

1 K&N HP3002 Filter or Equivelant

An optional Oil Cooler Kit, including additional fittings as needed, can be installed inline with the filter.

ATS was amongst the original instigators of the LSx swap movement, and one of the first to produce a simple and effective way to install one of these engines in an older muscle car. Made in the USA from 6061-T6 billet aluminum, ATS LSx Motor Adapter Plates are CNC machined for a precise fit. After final machining they are black powder coated for a long term trouble free finish. Simple and easy to install they're an easy step to getting your early model car up to late model speed. Sold in pairs with all necessary hardware.

A good set of headers can make all the difference in fit and function. Speedtech's headers are custom formed specifically for our ExtReme chassis and not only clear the frame rails, steering and other engine bay items, they provide fantastic ground clearance too. Made with high quality 321 Stainless Steel, they look great and that look will stand the test of time. Header tubes are 1 3/4" with slip fit 3" collectors in small block and LS applications and 1 7/8" tubes and 3.5" slip fit collectors for big blocks.

Be sure to ask your sales rep about these different options to customize your frame to your needs.
